It is (relatively) quick and easy to store a position in 24 bytes -- my chess program does that for opening books and learning and such. I'm sure one can shave a few bytes off with some effort. For 24 bytes, simply store a bitboard showing which squares are occupied, and then for each piece in order, 4 bits to say what piece (which gives 16 diffent pieces -- the extras can be used for cover side-to-move, castling rights and en passant). -paul
